PEG-CAP-DM macromonomers (A) were photopolymerized to create a cross-linked hydrogel network (B). Shown is an ideal network in which crosslinks 3 and 6 have been enzymatically cleaved by exogenously added lipase. (C) Experimental mass loss data and calculated mass loss profiles (solid lines) for hydrogels synthesized from PEG-CAP-DM macromonomers and incubated in solutions with (a) 1.0 mg/ml, (b) 0.4 mg/ml, (c) 0.2 mg/ml, and (d) 0.1 mg/ml Lipase PS 44.
